Chris & Julie Mesanko started this awesome journey in their hometown of Seaside Heights 40 years ago.  Coming to LBI in 1977, they would have never thought a concrete waterpark would grow into something so great!  The Mesanko's, who have been together for 50 years, run Thundering Surf Waterpark and Adventure Golf with both the daughter and son, Brooke (36) & Devin (34). They are all worked side by since their children were 14 years old. As Chris states, "They were born into it. They were playing on the waterslides as babies. It's a natural kind of thing, We sell fun!  It's pretty hard not to like the fun!"  The Mesanko's strive to provide your family with not only fun...but a clean and safe envirnonment, walking away with memories that will last a lifetime!

While Emotional Support Animals or Comfort Animals are often used as part of a medical treatment plan as therapy animals, they are not considered service animals under the ADA. These support animals provide companionship, relieve loneliness, and sometimes help with depression, anxiety, and certain phobias, but do not have special training to perform tasks that assist people with disabilities. Even though some states have laws defining therapy animals, these animals are not limited to working with people with disabilities and therefore are not covered by federal laws protecting the use of service animals.
